To all whom it may concern:

-Be it'known that I WILLIAM B. Crier- MA'N; of the borough of Manhattan, city, county, and State of New York, have invented certain new and. useful Improve,- me'ntsin Gas-Vashrs, of which the following' is a :full, clear, and exact specification,

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an apparatus for removing tar and other impurities from producer gas by which such gas may be rendered clean and fit to be used for power purposes. To such apparatus it is essential that a thorough and violent contact between the gas and the water used for washing be brought about, thus driving from the gas and precipitating the tar and other bituminous content held in suspension in the My present invention therefore resides in certain features of construction and co1nbi nation of parts which bring about this intimate and violent association of the water I. and gas and thoroughly expel the tarry matter and other impurities. All otthis will be fully brought out hereinafter and the novel features particularly pointed out in the claims. For this purpose reference is now i had-tothe accompanying drawings which represent, as an example, the preferred embodimcnt of my invention.

In such drawings; Figure 1. is a vertical section; Flg. 2 is a horizontal section on the view. l

.11 e ap aratus has. a casing preferably constructed' of sheet metal and cni'nprising anupwardly flaring body' part 10 of circular; cross section surmounted by a cylindi'Icalc'ollar 11 which 1n turn carries the cir-z ciilar blowing casing 12 having a tangentially d' out-let nozzle 14:.

ttachedv to a supporting clement (not we) Above this collar runs a collar 16 iclihas abearing on the collar 15 and is attached to a vertical shaft 17 extending downward through "a stufling box I 18* onftop'f of the blower housingflil and throiigh thehousing 10 to a point near the H anieaaj at 7 '1 h ndicates, a collar which is adapt-ed to \Vithin the housing .10 is a circular bafile plate 20 having an opening 21 in the center thereof through which the shaft 17 passes. The bottom of the casing l2 has a central opening 22 therein through which the shaft 17 also passes. lower end in the lower part of the housing 10 vertical, radial. fan blades 23 fastened to the shafthy, means of'arins 2 4 and a hub 25. Fastened to the upper edges of these blades is a circular battle plate 26' which turns with the blades and which, carries at its pcriphc y a number of down-stroking splash-' carry a circular baffle plate 31 which r0 The shaft 17 carries at its fates with them and which itself carries vex tical radial blades 32- also rotating.

Within the housing 12 and fastened to the shaft llis a centritugah high pressure blower 33 which draws the gas through the orifice 22 and forces it out through the tangential nozzle 14. a

A drain pipe 34, leads from the out-let 14 back into the collar 11 and housing 10 al.-

lowing any moisturein the out-let i l to re turn to the washer proper. 37 indicates a water supply pipe which encircles the up per part of the housing 10 and, as shown in Fig. 2, has a number of connections 35 passing into the upper part of the housing 1.0 and turned so that they discharge the 'ater in. the direction of revolution of the shaft 17 and its attachments.

Eltiiudicates baflle ribs which are: spirally disposed and. fastened to the interior walls oi" tl'ie-housiug 10 above; and below .the central wall 20. These battles are so arranged. relatively to the direction of rotation of the fans that below the partition or wall 20 the swirlin g gas and water are caused'to flow ipward along the battle ribs, while above suchgwalls the battle I'll)? cause a down-flow at tlio c cleincntsl This, it .will be seen,

' a nd gas. to be :thrown ha ck whereby 3 increasing the,

agitation and confusion within the washer upon which its successful operation depends.

The operation of the apparatus may be traced as follows: The gas is supplied to the lower part of the housing and streams of water are introduced through the nozzles I The shaft 17 is rotated at a high speed with the result that the blower 33 draws the gas rapidly into the housing 12. However, in passing through the housing 10 the gas first encounters the blades 23 and takes up the rotation thereof, so that it is thrown out to the sides of the housing 10 by contrifugal force. As it rises it is again baflied by the splashers 27and it encounters the water' falling through 'the housing 10. This water is also swirled around by the rotation of the blades and this brings it into violent contact with'the gas, both the Water and gas being forced against each other and moving in opposite directions. The gas then passes through the opening 21 and again en counters the water in a violent splashing motion caused by the blades 28 and 32- and thebafiie 31. In this manner the gas is again subjectedto the violent and intimate association with the water as described. In the end the gas reaches the housing 12 and is discharged. In this way the tarry and bituminous matter is driven from the gas and the gas is cleansed. The agitation abovedescribed is enhanced by the inclined bafiie ribs 36 which, as has been described. are fastened to the walls of the housing 10 and are inclined in such a manner that they, the direction of rotation bein fixed, stroke up and down against each other or rather cause the water and gas when moving in a circulat path, to flow upward. along the lower walls of the housing and downward along the upper walls. It will further be observed that the centrifugal action of the fans 28 and 32 tends to throw outward the tar, water and other solid. matter, while the exhauster 33 pulls the gas inward against this tendency. This brings about an effectual separation of the gas from the solid matter in suspension therein.

Having thus describedmy invention what" I claim as new and desire to secure by Letters. Patent of the United states, is:

1. A gas washer, having ahousing wit-L- a gas inlet at one end, an outlet at the other. an exhauster at the outlet. a water supply and means for baflling and swirling the gas and water comprising a. fan, a baflier attached to and rotatin therewith and inclined splashers carried by and projecting from the bafller. i

2. A gas-washer'having ahousing, a water supply, means for pulling the as 'through'the housing against the water ow I therein, a fan operating within the/housing,

A gas washer having a"housing."with a gas inlet and outlet, a water supply, means for pulling the gas through the housing contrary to the direction of the water flow, means for swirling the gas and water in' the housing and inclined battle ribs attached to the interior walls of the housing 4. A gas washer having a housing with a gas inlet and outlet, in water supply, means 'for pulling the gas througl the housing contrary to the direction of the water flow. means for swirling the gas and water in the housing and inclined baffle ribs atta ched to the interior walls of the housing, said balile ribs being disposed with regard to the direction of the swirling motion to cause an up and down or reverse flow of the gas and water.

5. A gas washer having a housing with a gas inlet and outlet, a water supply, means for pulling the gas through the housing in direction contrary to the water flow, a fan in the housing. a battle plate attached to the fan and splashers projecting out from the periphery of the plate.

A. gas washer having a housing with a gas inlet and outlet, a water supply, means for pulling the gas through the housing in direction contrary to the water flow. a fan in the housing. a. bafile plate attached to the fan and spla-shers projecting out from the periphery of the plate. said splashers being inclined or feathered so as to exert a tendency to throwthe gas and water opposite the-direction of the gas flow. r .-7.
